Math Problem Statement

Given the one-to-one function f(x) = ³√(1 - x), find f⁻¹(x).

Solution

To find the inverse of the function f(x)=1x3f(x) = \sqrt[3]{1 - x}, we need to solve for xx in terms of yy and then interchange xx and yy.

Step-by-Step Solution

  1. Start with the function: y=1x3y = \sqrt[3]{1 - x}

  2. Isolate the cube root: y3=1xy^3 = 1 - x

  3. Solve for xx: x=1y3x = 1 - y^3

  4. Interchange xx and yy to find the inverse function: y=1x3y = 1 - x^3

  5. Write the inverse function: f1(x)=1x3f^{-1}(x) = 1 - x^3

Final Answer

The inverse function is: f1(x)=1x3f^{-1}(x) = 1 - x^3
